TECHNICAL FIELD

The present disclosure relates to the field of display technology, andin particular to a screen of user equipment (UE), a screen structure, amethod and apparatus for controlling a screen of UE, and UE.

BACKGROUND

There has been a pursuit of an increasingly higher screen ratio in themobile phone industry. Expectation is to produce a mobile phone with ascreen ratio close to 100%.

A key to improving and maximizing a screen ratio of a mobile phone is toarrange a functional device such as a camera, an earphone, a lightsensor, a distance sensor, a fingerprint sensor, etc.) on a front panelof the mobile phone reasonably. It is conceived to arrange thefunctional device below the screen of the mobile phone, such that spaceon the front panel of the mobile phone that would have been occupied bythe functional device become fully available, thereby improving thescreen ratio.

However, some optical devices, such as a camera, a light sensor, aninfrared transmitter, an infrared receiver, etc., may have to receive ortransmit light in work. When such optical devices are arranged below thescreen of a mobile phone, such optical devices may have degraded workperformance, or even fail to work properly, under impact of translucenceof the screen of the mobile phone.

FIG. 1 is a schematic diagram of a screen of user equipment (UE)according to an exemplary embodiment. For example, the UE may be amobile phone. As shown in FIG. 1, the screen may include a substrate 10and a display layer 20 located on top of the substrate 10.

The display layer 20 may serve to implement a display function of thescreen. The display layer 20 may include a primary display area 21 and asecondary display area 22. The primary display area 21 and the secondarydisplay area 22 both have the display function. There may be one or moresecondary display areas 22. In FIG. 1, one secondary display area 22 isshown for illustration purpose.

The display layer 20 may include two distinct types of display areas,i.e., the primary display area 21 and the secondary display area 22. Theprimary display area 21 and the secondary display area 22 may beintegral parts of one unified physical structure. That is, the displaylayer 20 may be one whole structure without being divided into multipleseparate components.

If the display layer 20 includes multiple separate components, which arestitched together to form the display layer 20, then there may be a seamat a joint therein, ultimately leading to a seam between contentsdisplayed by the respective components. Consequently, no integratedseamless display of content by the whole display layer 20 can beachieved.

However, as the primary display area 21 and the secondary display area22 may be integral parts of one unified physical structure, there may beno seam between the two. Therefore, no seam may exist between contentdisplayed by the primary display area 21 and content displayed by thesecondary display area 22 Thus, integrated seamless display of contentby the whole display layer 20 may be achieved.

The primary display area 21 may include multiple pixels. The secondarydisplay area 22 may include one or more pixels. In general, a pixel mayinclude sub-pixels of three different colors, i.e., Red (R), Green (G),and Blue (B). That is, a pixel may include at least one red sub-pixel,at least one green sub-pixel, and at least one blue sub-pixel. In someembodiments, a pixel may include sub-pixels of one color. For example, apixel may include a sub-pixel of any one color of R, G, or B. In someembodiments, a pixel may include sub-pixels of two colors. For example,a pixel may include sub-pixels of any two colors of R, G, or B. In someembodiments, a pixel may include, in addition to at least one redsub-pixel, at least one green sub-pixel, and at least one bluesub-pixel, a sub-pixel of at least one other color, such as at least onewhite sub-pixel. The subject disclosure sets no limit as to the colorand the number of sub-pixels contained in a pixel.

A form of pixel distribution in the secondary display area 22 may differfrom that in the primary display area 21. The form of the pixeldistribution may refer to the form of distribution of sub-pixels. Theform of the pixel distribution may include, but is not limited to, atleast one of a size of a pixel, an arrangement of pixels, or a densityof pixel distribution. The size of a pixel in the secondary display area22 may differ from the size of a pixel in the primary display area 21.That is, the size of a sub-pixel in the primary display area 21 and thesize of a sub-pixel in the secondary display area 22 may differ. Asub-pixel in the secondary display area 22 may be greater in size than asub-pixel in the primary display area 21. The arrangement of pixels inthe secondary display area 22 may differ from the arrangement of pixelsin the primary display area 21. That is, an arrangement of sub-pixels inthe primary display area 21 and an arrangement of sub-pixels in thesecondary display area 22 may differ. For example, sub-pixels in theprimary display area 21 may be arranged according to a Deltaarrangement. For example, sub-pixels in the secondary display area 22may be arranged according to a standard Red-Green-Blue (RGB)arrangement. The density of pixel distribution in the secondary displayarea 22 may differ from the density of pixel distribution in the primarydisplay area 21. That is, the density of sub-pixel distribution in theprimary display area 21 and the density of sub-pixel distribution in thesecondary display area 22 may differ. For example, the density ofsub-pixel distribution in the primary display area 21 may be greaterthan the density of sub-pixel distribution in the secondary display area22.

As shown in FIG. 2, the secondary display area 22 may include nsub-pixel sequences 23. Each of the n sub-pixel sequences 23 may includeat least two sub-pixels 24. Any sub-pixel sequence 23 may includesub-pixels 24 of identical color. The n may be a positive integer. Asub-pixel 24 may in general be of any of color R, G, or B. A sub-pixelsequence 23 may be a red sub-pixel sequence, a green sub-pixel sequence,or a blue sub-pixel sequence. A red sub-pixel sequence may include redsub-pixels. A green sub-pixel sequence may include green sub-pixels. Ablue sub-pixel sequence may include blue sub-pixels.

The secondary display area 22 may include at least two sub-pixels ofidentical color that share one wire. For example, sub-pixels A, B, and Cas illustrated in FIG. 2 may be of one color. For example, the 3sub-pixels may all be red sub-pixels, or may all be green sub-pixels, orall be blue sub-pixels. And, the 3 sub-pixels may share one wire. Thewire may refer to a power wire and/or a signal line for controllingdisplay by a sub-pixel. A power wire may serve to provide a sub-pixelwith voltage. A signal line may serve to provide a sub-pixel with asignal for controlling a pixel value, such as brightness or a grayscale, etc. The signal line may also be referred to as a data line.

In the above embodiments, a display layer of one whole structure may beformed on a substrate. The display layer may be divided into a primarydisplay area and a secondary display area by a manufacturing process. Aform of pixel distribution in the secondary display area may differ fromthat in the primary display area. The secondary display area may includeat least one sub-pixel sequence. Each of the at least one sub-pixelsequence may include at least two sub-pixels. Any of the at least onesub-pixel sequence may include sub-pixels of identical color. Thesecondary display area may include at least two sub-pixels of identicalcolor sharing one wire. Therefore, there are a decreased number of wiresin the secondary display area, with optimized wire layout, such thatthere are a decreased number of devices such as a holding capacitor, aThin Film Transistor (TFT), etc., in the secondary display area, therebyincreasing transmittance of the secondary display area. Thus, one ormore optical devices, such as a camera, a light sensor, a proximitysensor, an optic transmitter, an optic receiver, etc., may be arrangedbelow the secondary display area, to provide optimal work performance.

In exemplary embodiments, shown in FIG. 3, a sub-pixel 24 in thesecondary display area 22 may be greater in size than a sub-pixel 21 ain the primary display area 21. For example, the sub-pixel 24 in thesecondary display area 22 may be greater in length than the sub-pixel 21a in the primary display area 21. For example, the sub-pixel 24 in thesecondary display area 22 may be greater in width than the sub-pixel 21a in the primary display area 21. The length of a sub-pixel may be thelength of a side of the sub-pixel along a crosswise direction. The widthof a sub-pixel may be the length of a side of the sub-pixel along alengthwise direction.

The sub-pixel 24 in the secondary display area 22 may be equal in lengthto the sub-pixel 21 a in the primary display area 21, and greater inwidth than the sub-pixel 21 a in the primary display area 21. Forexample, the sub-pixel 24 in the secondary display area 22 may have awidth that is 2 times, 2.5 times, 3 times, 4 times, etc., of the widthof the sub-pixel 21 a in the primary display area 21, which is notlimited in the embodiments.

The sub-pixel 24 in the secondary display area 22 may be equal in widthto the sub-pixel 21 a in the primary display area 21, and greater inlength than the sub-pixel 21 a in the primary display area 21. Forexample, the sub-pixel 24 in the secondary display area 22 may have alength that is 2 times, 2.5 times, 3 times, 4 times, etc., of the lengthof the sub-pixel 21 a in the primary display area 21, which is notlimited in the embodiments.

The sub-pixel 24 in the secondary display area 22 may be greater in bothwidth and length than the sub-pixel 21 a in the primary display area 21.For example, the sub-pixel 24 in the secondary display area 22 may havea width that is 2 times, 2.5 times, 3 times, 4 times, etc., of the widthof the sub-pixel 21 a in the primary display area 21, and may have alength that is 2 times, 2.5 times, 3 times, 4 times, etc., of the lengthof the sub-pixel 21 a in the primary display area 21, which is notlimited in the embodiments.

As the sub-pixel in the secondary display area 22 may be greater in sizethan the sub-pixel in the primary display area 21, the density of pixeldistribution in the secondary display area 22 will be less than thedensity of pixel distribution in the primary display area 21. In thisway, the number of wires in the secondary display area 22 may beminimized, with optimized wire layout, and an inter-pixel PixelDelineation Layer (PDL) may be allowed to take on a shape as regular andbulky as possible, such that a translucent area (which may includesub-pixels and an area taken up by the PDL) in the secondary displayarea 22 may acquire better light transmission performance, and greaterreflectivity and a greater index of refraction. Thus, one or moreoptical devices, such as a camera, a light sensor, a proximity sensor,an optic transmitter, an optic receiver, etc., may be arranged below thesecondary display area to work properly.

Although a sub-pixel in the secondary display area 22 may be greater insize than a sub-pixel in the primary display area 21, given that thesecondary display area 22 may occupy an area the ratio of which to thearea of the whole screen is very small, in general only a single colormay be displayed in the secondary display area 22 and in an area of theprimary display area 21 that is around the secondary display area 22.Therefore, there will be barely any impact on the display result in thewhole screen.

Not each sub-pixel in the secondary display area 22 has to be greater insize than a sub-pixel in the primary display area 21. One or moresub-pixels in the secondary display area 22 may be equal to, or evensmaller than, a sub-pixel in the primary display area 21 in size, whichis not limited in the embodiments.

In addition to the size of a pixel therein, the secondary display area22 may differ from the primary display area 21 in terms of anarrangement of pixels, a density of pixel distribution, or another formof pixel distribution therein.

In the above embodiments, as the sub-pixel in the secondary display areamay be greater in size than the sub-pixel in the primary display area,the density of pixel distribution in the secondary display area may beless than the density of pixel distribution in the primary display area.In this way, the number of wires in the secondary display area may beminimized, with optimized wire layout, and an inter-pixel PixelDelineation Layer (PDL) may be allowed to take on a shape as regular andbulky as possible, such that a translucent area (which may includesub-pixels and an area taken up by the PDL) in the secondary displayarea may acquire better light transmission performance, and greaterreflectivity and a greater index of refraction. Thus, one or moreoptical devices, such as a camera, a light sensor, a proximity sensor,an optic transmitter, an optic receiver, etc., may be arranged below thesecondary display area to work properly.

The screen of the UE may have further characteristics as follows.

The secondary display area 22 may include n sub-pixel sequences. The nmay be an integer greater than 1. The n sub-pixel sequences may bearranged one by one along a target direction. The target direction maybe vertical or horizontal. Sub-pixels included in a sub-pixel sequencemay be arranged one by one along a first direction. The n sub-pixelsequences may be arranged one by one along a second direction. The firstdirection and the second direction may be perpendicular to each other.For example, the first direction may be horizontal, and then the seconddirection may be vertical. Also for example, the first direction may bevertical, and then the second direction may be horizontal. For example,in FIG. 2, the secondary display area 22 may include 6 sub-pixelsequences 23. Each sub-pixel sequence 23 may include multiple sub-pixels24. Sub-pixels 24 included in each sub-pixel sequence 23 may be arrangedone by one along a horizontal direction. The 6 sub-pixel sequences 23may be arranged one by one along a vertical direction.

The n sub-pixel sequences may include at least one red sub-pixelsequence, one green sub-pixel sequence, and one blue sub-pixel sequence.The at least one red sub-pixel sequence, one green sub-pixel sequence,and one blue sub-pixel sequence may be arranged alternately one by onealong the target direction.

As shown in FIG. 4, in the secondary display area 22, sub-pixelsincluded in each sub-pixel sequence may be arranged one by one along ahorizontal direction. The secondary display area 22 may include at leastone red sub-pixel sequence, one green sub-pixel sequence, and one bluesub-pixel sequence. The sub-pixel sequences may be arranged alternatelyone by one along a vertical direction in order of one red sub-pixelsequence, one green sub-pixel sequence, one blue sub-pixel sequence, . .. .

As shown in FIG. 5, in the secondary display area 22, sub-pixelsincluded in each sub-pixel sequence may be arranged one by one along avertical direction. The secondary display area 22 may include at leastone red sub-pixel sequence, one green sub-pixel sequence, and one bluesub-pixel sequence. The sub-pixel sequences may be arranged alternatelyone by one along a horizontal direction in order of one red sub-pixelsequence, one green sub-pixel sequence, one blue sub-pixel sequence, . .. .

When the secondary display area 22 includes at least one red sub-pixelsequence, one green sub-pixel sequence, and one blue sub-pixel sequence,the three primary colors in the secondary display area 22 may be mixed,displaying a distinct color. When the secondary display area 22 includesthe sub-pixel sequence(s) of one or two colors, the color that can bedisplayed by the secondary display area 22 may be limited. For example,when the secondary display area 22 includes the red sub-pixelsequence(s), the secondary display area 22 may display red. For example,when the secondary display area includes the red sub-pixel sequence(s)and the green sub-pixel sequence(s), the secondary display area 22 maydisplay red and green, a color acquired by mixing red and green.

The embodiments herein set no limit as to a ratio of length to width ofa sub-pixel in the secondary display area 22. For example, the ratio oflength to width may be 1:1, 1:2, 1:3, 2:1, 3:1, or any other ratio.Sub-pixels in the secondary display area 22 may be identical or maydiffer in size. Sub-pixels of one color may be identical or may differin size. Sub-pixels of distinct colors may be identical or may differ insize.

Of the n sub-pixel sequences of the secondary display area 22, there maybe at least one sub-pixel sequence, center points of respectivesub-pixels included in the at least one sub-pixel sequence being locatedon one straight line. For example, in examples of FIG. 4 and FIG. 5, ofthe n sub-pixel sequences of the secondary display area 22, anysub-pixel sequence may include sub-pixels with respective center pointsall located on one straight line.

Of the n sub-pixel sequences of the secondary display area 22, there maybe at least one sub-pixel sequence, not all center points of respectivesub-pixels included in the at least one sub-pixel sequence being locatedon one straight line. For example, in the example of FIG. 6 or FIG. 7,for any one sub-pixel sequence of the n sub-pixel sequences of thesecondary display area 22, not all center points of respectivesub-pixels included in the any one sub-pixel sequence are located on onestraight line. In the secondary display area 22 as illustrated in FIG. 6and FIG. 7, a sub-pixel sequence may be formed by sub-pixels of onecolor connected by a curve.

Of the a sub-pixel sequences of the secondary display area 22, an i-thsub-pixel sequence may include a 2k-th sub-pixel with a center pointlocated on a first straight line and a (2k−1)-th sub-pixel with a centerpoint located on a second straight line. The first straight line and thesecond straight line may be parallel. The i may be a positive integer nogreater than the n. The k may be a positive integer. That is, centerpoints of even (such as the 2nd, the 4th, the 6th, etc.) sub-pixels maybe located on the first straight line, and center points of odd (such asthe 1st, the 3rd, the 5th, etc.) sub-pixels may be located on the secondstraight line. Taking the red sub-pixel sequence on the 1st line in FIG.6 or FIG. 7 as an example, center points of even sub-pixels may belocated on the first straight line L1. Center points of odd sub-pixelsmay be located on the second straight line L2. The first straight lineL1 and the second straight line L2 may be parallel.

FIG. 6 and FIG. 7 illustrate cases where not all center points ofrespective sub-pixels included in one sub-pixel sequence are located onone straight line when the n sub-pixel sequences of the secondarydisplay area 22 are arranged one by one along a vertical direction. Whenthe n sub-pixel sequences are arranged one by one along a horizontaldirection, not all center points of respective sub-pixels included inone sub-pixel sequence may be located on one straight line, either.

When center points of respective sub-pixels included in one sub-pixelsequence are located on one straight line, the wire may be simple, andpixel manufacture may get simpler. When not all center points ofrespective sub-pixels included in one sub-pixel sequence are located onone straight line, the wire may get more complicated. However, a betterdisplay result pray be achieved. For example, a display result may beachieved in the secondary display area 22 that is identical, or as closeas possible, to that in the primary display area 21.

If the secondary display area 22 can display a single color, i.e., candisplay one color at a time, then sub-pixels of identical color in thesecondary display area 22 may share one wire. As shown in FIG. 8,assuming that the secondary display area 22 includes sub-pixels ofdistinct colors R, C, B, all red sub-pixels in the secondary displayarea 22 may share one wire (referred to as the first wire S1). All greensub-pixels in the secondary display area 22 may share one wire (referredto as the second wire S2). All blue sub-pixels in the secondary displayarea 22 may share one wire (referred to as the third wire S3). Differentwires may be used for sub-pixels of different colors. That is, the firstwire S1, the second wire S2, and the third wire S3 may be three distinctwires. In this case, the secondary display area 22 may display R, G, B,or any one single color acquired as a mixture thereof. The secondarydisplay area 22 may include sub-pixels of one or two colors. Thesecondary display area may include a sub-pixel of another color inaddition to sub-pixels of distinct colors R, G, B. Regardless of thenumber of colors of sub-pixels included in the secondary display area22, sub-pixels of identical color in the secondary display area 22 maybe made to share one wire when the secondary display area 22 can displaya single color.

If the secondary display area 22 can display multiple colors, i.e., candisplay multiple colors at a time, then the secondary display area 22may include at least two sub-areas. Sub-pixels of identical color ineach of the at least two sub-areas may share one wire. Sub-pixels indifferent sub-areas may have separate wires. Each sub-area may includeone or more sub-pixels. As shown in FIG. 9, the secondary display area22 may be divided into 4 sub-areas 22 a. For example, the sub-area 22 aas shown in the upper right corner in FIG. 9 may include sub-pixels ofdistinct colors R, G, B. All red sub-pixels in the sub-areas 22 a mayshare one wire (referred to as the fourth wire S4). All green sub-pixelsin the sub-areas 22 a may share one wire (referred to as the fifth wireS5). All blue sub-pixels in the sub-areas 22 a may share one wire(referred to as the sixth wire S6). Different wires may be used forsub-pixels of different colors. That is, the fourth wire S4, the fifthwire S5, and the sixth wire S6 may be three distinct wires. Thus, eachsub-area 22 a may display R, G, B, or any one single color acquired as amixture thereof. The whole secondary display area 22 may includemultiple sub-areas 22 a. Each sub-area 22 a may display a single color.One single color or different single colors may be displayed in therespective sub-areas 22 a. Therefore, the whole secondary display area22 can display multiple colors. For example, in FIG. 9, each sub-area 22a may include sub-pixels of distinct colors R, G, B. A sub-area 22 a mayinclude sub-pixels of one or two colors. A sub-area may include asub-pixel of another color in addition to sub-pixels of distinct colorsR, G, B. No limit is set as to the number of sub-areas 22 a thesecondary display area 22 may include and how it is divided, which maybe designed as needed. When the secondary display area 22 can displaymultiple colors, sub-areas included in the secondary display area 22 maydisplay multiple color blocks, to meet more display demands.

In an embodiment, shown in FIG. 10, the display layer 20 may furtherinclude a transitional display area 25. The transitional display area 25may be located between the primary display area 21 and the secondarydisplay area 22. A form of pixel distribution in the transitionaldisplay area 25 may differ from that in the primary display area 21 orthat in the secondary display area 22. A sub-pixel in the transitionaldisplay area 25 may be greater in size than a sub-pixel in the primarydisplay area 21. A sub-pixel in the transitional display area may beless in size than a sub-pixel in the secondary display area 22.Sub-pixels in the transitional display area 25 may be identical or maydiffer in size. The closer a sub-pixel is to the secondary display area22, the greater it may be in size. The closer a sub-pixel is to theprimary display area 21, the less it may be in size. In this way, thetransition of a resolution between the primary display area 21 and thesecondary display area 22 may be made smooth and natural, improving thedisplay result of the whole screen.

Display in the primary display area 21, display in the secondary displayarea 22, and display in the transitional display area 25 may becontrolled separately. That is, the primary display area 21, thesecondary display area 22, and the transitional display area 25 may haveseparate wires. Thus, brightness and color displayed in the transitionaldisplay area 25 may be controlled separately. The primary display area21 and the secondary display area 22 may display related contentrespectively. The transitional display area 25 may not be powered, suchthat the transitional display area 25 may appear to be black, so as todisplay specific content.

Spacing between sub-pixels in the secondary display area 22 may beequal, or as close as possible, to spacing between sub-pixels in theprimary display area 21. For example, horizontal or vertical spacingbetween sub-pixels of one color in the secondary display area 22 may beequal, or as close as possible, to that in the primary display area 21.For the form of pixel distribution in the secondary display area 22 asshown in FIG. 6 or FIG. 7, a distance between the first straight lineand the second straight line may equal a distance between center pointsof two sub-pixels of identical color in the primary display area 21.This may help improve the display result of the whole screen.

No limit is set as to how sub-pixels in the primary display area 21 arearranged. Sub-pixels in the primary display area may be arrangedaccording to at least one of a Delta arrangement, a Pentile arrangement,or a standard Red-Green-Blue, RGB, arrangement.

No limit is set as to a shape of a section of the secondary display area22, which may be a regular shape such as of a rectangle, a roundedrectangle, a circle, etc., or an irregular shape such as of a waterdrop, an arc, etc.

In the embodiments illustrated in FIG. 1 to FIG. 10, the secondarydisplay area 22 is located on an edge or in the middle of the primarydisplay area 21, for illustration purposes only. In an embodiment, thesecondary display area 22 may be located next to a side of the primarydisplay area 21. In an embodiment, the secondary display area 22 may bejointed to the primary display area 21 closely. In an embodiment, thedisplay layer 20 may include both a secondary display area 22 at a gapin the primary display area 21, and a secondary display area 22 locatednext to a side of the primary display area 21.

The screen may have a regular shape. The regular shape may include anyone of a rectangle, a rounded rectangle, or a circle. The screen mayhave an irregular shape. The present disclosure sets no limit thereto.

When the display layer 20 includes multiplesecondary display areas 22, a functional device may be arranged belowone secondary display area 22, while no functional device may bearranged below another secondary display area 22. The same or differentfunctional device(s) may be arranged respectively below two distinctsecondary display areas 22. A camera and a proximity sensor may bearranged below one secondary display area 22. A fingerprint identifyingsensor may be arranged below another secondary display area 22.

By having at least two sub-pixels of identical color in the secondarydisplay area 22 share one wire, or having the sub-pixel in the secondarydisplay area 22 be less in size than the sub-pixel in the primarydisplay area 21, the number of wires in the secondary display area 22may be minimized with optimized wire layout, such that there are adecreased number of devices such as a holding capacitor, a Thin FilmTransistor (TFT), etc., in the secondary display area 22, therebyincreasing transmittance of the secondary display area 22. Thus, anoptical device may be arranged below the secondary display area to workproperly.

In an exemplary embodiment, a method for controlling a screen of UE maybe provided. The method may be executed by a driving IC of the screen, aprocessor in the UE, or interaction and collaboration of multiplecomponents with processing capability in the UE. The method may includea step as follows. A first synchronization signal may be sent to theprimary display area. A second synchronization signal may be sent to thesecondary display area.

The first synchronization signal and the second synchronization signalmay be for controlling simultaneous display of content by both theprimary display area and the secondary display area. The content mayalso be referred to as one display or one frame. The primary displayarea and the secondary display area may be controlled respectively bytwo different driving ICs or different parts of one driving IC.Therefore, to display different parts of content respectively by theprimary display area and the secondary display area, framesynchronization between the primary display area and the secondarydisplay area may be used to avoid impact on the display result due tothe primary display area and the secondary display area displayingdifferent frames.

With a screen of UE provided herein, content displayed in the primarydisplay area and content displayed in the secondary display area maycombine to form a complete display content, equivalent to that can bedisplayed by another screen with an identical size and an identicalshape as the screen, however not divided into the primary display areaand the secondary display area. With high transmittance of the secondarydisplay area, an optical device may be arranged below the secondarydisplay area to work properly. Thereby, an optical device, as well asanother functional device, that should have been deployed on a frontpanel of the UE, may now be arranged below the screen of the UE, withoutcompromising quality of display of the screen, such that the screenratio of the screen may get closer to or even reach 100%.

The method may further include a step as follows. A raw color componentof the content to be displayed in the primary display area may beacquired. A raw color component of the content to be displayed in thesecondary display area may be acquired. A corrected color component ofthe content to be displayed in the primary display area may be acquiredby performing Gamma correction on the primary display area. A correctedcolor component of the content to be displayed in the secondary displayarea may be acquired by performing Gamma correction on the secondarydisplay area. The corrected color component of the content to bedisplayed in the primary display area may be sent to the primary displayarea. The corrected color component of the content to be displayed inthe secondary display area may be sent to the secondary display area.

The primary display area and the secondary display area may bemanufactured with different properties (such as the form of the pixeldistribution). Therefore, the primary display area and the secondarydisplay area may use different color components to present one colorresult. The color component may include respective color components R,G, B. For example, when an upper layer application requires to displayon the screen a red area, one part of which on the primary display areadisplaying, the other part of which on the secondary display area, ifidentical color components (such as 255, 0, 0 corresponding respectivelyto R, G, B) are sent to the primary display area and the secondarydisplay area, the color displayed by the primary display area accordingto the color component 255/0/0 and that displayed by the secondarydisplay area according to the color component 255/0/0 may somehow appeardifferent to the naked eye. Therefore, by performing Gamma correctionrespectively on the primary display area and the secondary display area,the primary display area and the secondary display area may present theidentical color result, when one color is to be displayed.

Given a density of pixel distribution in the primary display area beinggreater than that in the secondary display area, i.e., a resolution ofthe primary display area being greater than that of the secondarydisplay area, in displaying different parts of content respectively bythe primary display area and the secondary display area, to have asmooth transition of a display result between the two display areas, atransitional display area may form between the primary display area andthe secondary display area. A display parameter of the transitionaldisplay area between the primary display area and the secondary displayarea may be determined according to the content to be displayed in theprimary display area and the secondary display area. The displayparameter may be sent to the transitional display area. The transitionaldisplay area may serve to display content according to the displayparameter.

The display parameter of the transitional display area may serve toprovide a smooth transition of a display result between the primarydisplay area and the secondary display area, avoiding a notabledifference between display results in the two display areas due toinconsistent resolutions, improving experience of a user in viewing thescreen.
